NICKEL PLATED HR® ON/OFF VALVE WITH 1/4" DIAMETER BARBED STEM
  • Nickel Plated to resist damage from most aggressive chemicals.
  • 1/4" Barbed Stem for attaching tubing, helps keep tubing in place.
  • Leak resistant seal in closed position, prevents sample loss. However, when stem is not closed, sample air passes into the ambient air outside valve.
  • Prices include Nickel Plated HR® ON/OFF Valve.
  • Use 3/16 ID tubing on stem.
  • Bags with grommets available.
  • Bags with multiple fittings available.
  • Custom sized bags available.

Valve/Fitting Features
  • Nickel Plated
  • Barbed stem for attaching tubing.
  • Leak resistant seal in closed position.


Film Key Features
FEP is one of the most chemically inert materials for making gas sampling bags. It works well in extreme temperatures ranging from -400 to 400 ºF; allowing it to be used in most stack sampling conditions. 5 mil FEP film is completely resistant to the most severe corrosives. Much more permeable than Multi-Layer or Tedlar®. FEP bags can be specified for applications involving corrosive gases.


Suggestion
  • Before use, thoroughly flush bags with ultra-pure nitrogen or zero air
  • During sampling, Fluoropolymer tubing and Fluoropolymer faced septums must be used in order to prevent sample loss.
  • Bags should not be filled to more than 80% of their maximum volume.
  • Charcoal (Black) Tedlar® bags should be used when sampling light sensitive compounds
  • Do not store compounds in bags long term due to the possibility that chemicals may adsorb onto the bag surface.
  • Bags should not be used to collect reactive or unstable compounds.
  • When shipping bags, do not air-ship unless the bags are stored in a pressurized area.


Film Properties
  • One of the most chemically inert materials available for making gas sampling bags
  • Maximum operating temperature: 400 ºF
  • Virtually transparent


Film Advantages
  • Works well in extreme temperatures ranging from -400 to 400 ºF; allowing it to be used in all stack sampling conditions
  • Heavier gauge (0.005) film is resistant to most severe corrosives as well as tolerates applications involving rough handling or difficult service conditions
  • Less expensive than PFA


Film Limitations
  • Poor long term storage stability for most VOC's and sulfur compounds
  • Much more permeable than Tedlar®, ALTEF, and Multi-Layer Foil bags
  • More expensive than Tedlar®, ALTEF, Multi-Layer Foil, and TFM bags
  • Lower tensile strength than Tedlar®


Valve/Fitting Benefits
  • Resists damage from most aggressive chemicals.
  • Helps hold tubing in place.
  • Prevents sample loss in closed position. However, when stem is not closed, sample air passes into ambient air outside valve.
